SOLDERiNG-TOOL.

SPECIFICATION forming part of Letters Patent No. 371,806, dated October 18, 1887.

Application filed February 2, 1887. Serial No. 226,215.

To aZZ whom it may concern:

Be it known that we, CHARLES L.WAGANDT and J OHN S. HULL, both of the city of Baltimore, in the State of Maryland, have invented certain Improvements in Soldering-Tools, of which the following is a specification.

This invention relates to certain improvements in that class of soldering-tools in which the soldering-block is kept constantly in a heated condition by means of a flame applied directly thereto, and in which the flame is produced by the combination of jets of gas and atmospheric air, which are conducted to the base of the soldering-block through pipes.

The said invention consists in certain details of construction of the said soldering-tool and in improved means for suspending the same, [as will hereinafter fully appear.

In the further descriptionof the said invention which follows referenceis made to the accompanying drawings, forming a part'hereof, and in which- Figure I is a view of the improved soldering-too], together with the means used for its suspension and the pipes through which air and gas'are conducted to the soldering-block to heat the same. Fig. II is an enlarged exterior view of the improved soldering-tool, and Fig. 111 is a longitudinal section of the same. Fig. IV is a view of the tool as seen from the point of the soldering-block. Fig.V is a section of Fig. II, taken on the dotted line :0 w, the soldering-block being removed.

Fig. VI illustrates a modification in the construction of a part of the suspensory device, as will hereinafter appear.

Similar letters of reference indicate similar parts in all the figures.

In the said drawings, A is the soldering block, which is shown as of the centrallypointed description. It is evident, however, that the shape of the soldering-block, as far as the soldering end is concerned, has no bearing on the invention consequently any block adapted to fit in the holding device could be substituted for the one shown without materially affecting the character of the invention.

B is a combustion-chamber, into one end of which the soldering-block is adapted to fit and be secured.

This combustionchamber is in two parts, a and b, and into the one a the sol- (No model.)

dering-block is inserted. The section b of the said chamber is screwed into the section a and receives the pipe 0, the end of which is threaded to admit of the connection. The other end of the pipe G is provided with a gas-chamber, D, having a nozzle, E, to which the flexible pipe F is attached, and into the outer end of the gas chamber is screwed the air-nozzle G, adapted for attachment to the flexible airpipe H.

The pipe G is provided with a tightly-fitting core, I, of some polygonal crosssection, preferably triangular, which forms the passages c for the gas to escape from the gaschamber to the combustion-chamber B, and the part of the core which passes through the gas-chamber is reduced in size and attached to the air-nozzle, or the core is fitted with an interior pipe, J, which couples the air-nozzle with the combustion-chamber, as shown in Fig. III of the drawings. The section a of the chamber has a flange, d, on its front end, and this flange is arched at, say, four places in its circumference, to form, in connection with apertures e in the head of the chamber, means of escape for flame from the combustionchamber. These arches are shown in Fig. V and denoted by f. The combustion-chamber has also holes g in its wall to admit air to the flame. The base of the soldering-block is of spherical shape in order that the flame playing thereon may not be deflected to the side of the combustion-chamber, but may pass around and lengthwise of the block.

It will be understood that the air can be admitted through the passages c to the combustion-chamber and the gas through the central pipe J without departing from the spirit of the invention. The outer pipe has a locknut, h, in order that when the distance between the end of the said pipe and the base of the soldering-block is adjusted to give the best .ment. By this means the height of the soldering-tool may be arranged to suit any character of work. The complete suspensory devices are shown only in Fig. I.

It will be seen that in suspending the soldering-tool by means of the rod, as described, there can be no strain on the air and gas pipes.

The soldering-block is preferably held to the section a of the combustion-chamber by means of threaded fingers n n, which extend from the periphery of the said section and are bent downward, so as to come in contact with the soldering-block, at which point they are surrounded by a nut, L. The said block can, however, be held by a set-screw, 0, in which case the threaded fingers would not be absolutely necessary; but they could be used as additional means to form the union of the two parts of the tool.

I In Figs. I and VI is shown a connection for the suspensory rod, which is made to extend practically the whole length of the space between the lock-nut h and the handle M. With this connection a longitudinal movement of the soldering-tool can be obtained independently of the suspensory device, and the tool may be balanced in a horizontal position bymoving-the eye of the suspensory rod to the arched center of the connecting-piece.

We claim as our invention- 1. In a soldering-tool, a combustion-chamber, a soldering-block inserted in the said chamber, a pipe extending from the said combustion-chamber to a gas-chamber having a gas-nozzle, and a core having some polygonal cross-section inclosed in the said pipe and provided with a central hole extending longitudinally of the same, which core passes through the said gas-chamber and is connected to a nozzle adapted to convey air to the said combustion-chamber, substantially as and for 40 the purpose specified.

2. In a soldering-tool, a combustion-chambercombined with a soldering-block having a spherical inner end held within the said chamber, the chamber being provided with openings through which flame escapes to the surface of the soldering-block at a point outside of the said chamber, substantially as and for the purpose specified.

3. A soldering-tool having a rod provided with means by which it may be suspended, formed in two parts with right and left threaded ends connected by means of a nut, substantially as and for the purpose specified.

4. A soldering'tool connected by means of a flexible pipe to a source of gas-supply, combined with a vibratory suspensory device having a universal joint, whereby strain is removed from the flexible pipe and the tool may be moved in any desired direction while in 6Q operation, substantially as and for the purpose specified.
